Question

I don' understand this question
If MI = 15 m, SM = 20 m, and TM = 9 m, what is the value of RM?

12 m

18 m

20 m

30 m

Answer 1

do u have a diagram??

Answer 2

that is the picture it come with

Answer 3

erm it use pythagoras for IT....do you know anything about the relationship between parallel hypotenuses ???

Answer 4

no not really i am just really confused in how to find the answer

Answer 5

i think it is 18 but idk if that is right

Answer 6

think of the triangle SRM as the little triangle ITM scaled by some factor.

If you find the scale between two corresponding sides, then you can use that scale same for all other sides.

MI corresponds to MS. the scale is 4/3. right?

Answer 7

(MI/3) * 4 = MS.
then (MT/3)*4 = RM

Answer 8

but the answers are
12 m

18 m- and i think this is the right one

20 m

30 m

Answer 9

im think the answer is 12...based frm reemii explanation
the length of IT= 3 root 34
if you multiply that by 20/15...u get SR
once u have SR use pythagoras becos u have SM....to find MR

Answer 10

ok i see what i did wrong thank you

Answer 11

no probzz i actually learnt something myself!!

Answer 12

:D

Answer 13

Answer 20

use the cosine rule....the answer is 53.13

Answer 21

so then was i correct

Answer 22

yep!!
